Hi Andre & all
Just a though but you might want to check your jackd timeout (qjackctl->setup->settings->timeout).I was having the exact same problem running ardour from gdb (it was freezing at ‘Scanning folders for bundled LV2s…’ etc).
It turns out I forgot to increase my jackd timeout (as one does when running through gdb).
I bumped it up to 5000ms and it loaded no problems.
While it was hanging I looked at the backtrace in gdb,

I guess maybe it was waiting for something to come back from jackd to say its port is registered (or something) but jackd has timed out and given up(?). Either way increasing the timeoue seemed to do the trick for me.
Of course, your hang may well be due to some other reason(s) completely.
The only way to tell for sure is to get a backtrace as per the link mentioned previously in this thread etc…
(run ardour in gdb, ctrl c at hand then enter ‘bt’ …i think…)
But first up the jackd timeout, see if it makes any difference.
Hope this helps.
By the way, off topic I know but I’ve just setup Ardour in last week & am playing around with it. What a brilliant piece of audio software!
Thanks so much & well done to all involved, am blown away by your work and its quality.
Music can only benefit as a result.
I’m really looking forward to leaving windows behind & moving to ardour & linux for producing music form here on.
Cheers, Brian
